Description

Technical Field

[0001] This utility model relates to the field of power maintenance tools and equipment, and in particular to a modular insulating short rod. Background Technology

[0002] In power maintenance operations, insulating rods are crucial tools for ensuring the safety of personnel when handling live equipment. They are widely used in the operation of drop-out fuses and for clearing foreign objects from power lines. To ensure insulation performance and mechanical strength, existing insulating rods primarily employ an integrated structure of the rod body and operating head. This integrated structure results in a single function for the insulating rod. When various operations such as clamping, hooking, and pushing / pulling are required at the maintenance site, personnel must carry multiple insulating rods equipped with different operating heads. This leads to numerous and heavy tools on-site, increasing the physical exertion of the workers. The frequent replacement of entire insulating rods also significantly slows down the progress of emergency repairs.

[0003] Although some improved insulating rods adopt a detachable operating head design and use simple threaded or pin connections, there is a risk of loosening and falling off the connection between the operating head and the rod body under long-term reciprocating operation and vibration environment. Insufficient rigidity of the connection structure will cause the operating head to shake when under force, making it difficult to meet the strict requirements of operation accuracy and safety for high-altitude power operations.

[0004] Therefore, this utility model proposes a modular insulating short rod to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems in the existing technology, such as the single function of the insulating rod leading to heavy tools for operators, and the insufficient rigidity of the connection structure of the detachable insulating rod operating head, which is prone to loosening and shaking and thus poses a safety hazard, this utility model aims to provide a modular insulating short rod with an improved structure that can effectively solve the above problems.

[0008] Preferably, the splicing mechanism includes a fixing ring fixedly connected to the top of the outer wall of the first insulating rod, the bottom of the outer wall of the second insulating rod, and the upper and lower sides of the outer wall of the splicing rod. Half-ring one and half-ring two are provided at the connection between the first insulating rod and the splicing rod, and at the connection between the splicing rod and the second insulating rod.

[0009] Preferably, the left front end of the first semi-ring sleeve is rotatably connected to the second semi-ring sleeve, and the first and second semi-ring sleeves are closed to form an annular connecting sleeve.

[0010] Preferably, the upper and lower ends of the right side of the second semi-ring sleeve are both connected to a threaded shaft, one end of which passes through the second semi-ring sleeve and the first semi-ring sleeve and extends to the outside of the first semi-ring sleeve. The end of the threaded shaft extending to the outside of the first semi-ring sleeve is threaded to a nut.

[0011] Preferably, both the bottom end of the second insulating rod and the bottom end of the splicing rod are fixedly connected to positioning pins. The positioning pin at the bottom end of the splicing rod is slidably connected to the top of the inner wall of the first insulating rod, and the positioning pin at the bottom end of the second insulating rod is slidably connected to the top of the inner wall of the splicing rod.

[0012] Preferably, the bidirectional lead screw is rotatably connected to the inner wall of the standard mounting base, and the threads at both ends of the bidirectional lead screw have opposite directions. When the bidirectional lead screw rotates, it drives the two sliders to move towards or away from each other along the inner wall of the standard mounting base.

[0013] Preferably, the extrusion block has a guide slope on the side near the center of the dovetail groove, and the inner wall of the extrusion groove has a force-bearing slope that abuts against the guide slope. When the slider moves, it extrudes the dovetail block through the extrusion block.

[0022] Please refer to Figure 2 and Figure 3 The installation mechanism 2 includes a standard mounting base 21 fixedly connected to the top of the second insulating rod 5 and a base 22 fixedly connected to the bottom of the operating head 6. The standard mounting base 21 serves as the docking platform for the operating head 6, and the base 22 serves as the connection interface for the operating head 6. A dovetail groove 24 is provided on the top of the standard mounting base 21, and a dovetail block 23 is fixedly connected to the bottom of the base 22. The dovetail block 23 is slidably connected to the inner wall of the dovetail groove 24.

[0023] Please refer to Figure 2 and Figure 4To address the issues of stable connection and ease of operation of the pole, the modular insulating short pole also includes a splicing mechanism 3. The splicing mechanism 3 is located between the first insulating pole 1 and the splicing pole 4, and between the splicing pole 4 and the second insulating pole 5. The splicing mechanism 3 includes a fixing ring 31 fixedly connected to the top of the outer wall of the first insulating pole 1, the bottom of the outer wall of the second insulating pole 5, and the upper and lower sides of the outer wall of the splicing pole 4. A semi-ring sleeve 32 is provided at the interface between the first insulating pole 1 and the splicing pole 4, and at the interface between the splicing pole 4 and the second insulating pole 5. A semi-ring sleeve 33 is rotatably connected to the left front end of the semi-ring sleeve 32.

Multiple annular grooves 34 are provided on the inner walls of the semi-ring sleeve 32 and the semi-ring sleeve 33.

One end of the threaded shaft 35 passes through the second semi-ring sleeve 33 and the first semi-ring sleeve 32 and extends to the outside of the first semi-ring sleeve 32. The end of the threaded shaft 35 extending to the outside of the first semi-ring sleeve 32 is threadedly connected to a nut 36. By tightening the nut 36, the first semi-ring sleeve 32 and the second semi-ring sleeve 33 are driven to tighten inward, thereby using the ring groove 34 to lock the fixed ring 31. The bottom end of the second insulating rod 5 and the bottom end of the splicing rod 4 are both fixedly connected to positioning pins 37. The positioning pin 37 located at the bottom end of the splicing rod 4 is slidably connected to the top of the inner wall of the first insulating rod 1, and the positioning pin 37 located at the bottom end of the second insulating rod 5 is slidably connected to the top of the inner wall of the splicing rod 4. The positioning pins 37 play a guiding and initial positioning role during the splicing process.

[0025] In a preferred embodiment, and as a preferred embodiment of the core driving component inside the mounting mechanism 2, the bidirectional lead screw 26 is rotatably connected to the inner wall of the standard mounting base 21 and located between the two sliders 25. The left and right sections of the bidirectional lead screw 26 are provided with external threads in opposite directions. The inner walls of the two sliders 25 are respectively provided with internal thread holes that match the threads at the corresponding positions of the bidirectional lead screw 26. By rotating the bidirectional lead screw 26, the two sliders 25 can be driven to move synchronously towards each other or synchronously away from each other along the guide rail on the inner wall of the standard mounting base 21, ensuring the uniformity of the force on both sides of the base 22.

[0026] As a preferred embodiment, in order to further improve the connection rigidity and anti-loosening ability of the operating head 6 after installation, the side of the extrusion block 27 near the center of the dovetail groove 24 is set as a guide slope, and the inner wall of the extrusion groove 28 on the dovetail block 23 is set as a force-bearing slope with the same slope as the guide slope. When the slider 25 drives the extrusion block 27 to move inward into the extrusion groove 28, the extrusion block 27 uses the wedge effect between the guide slope and the force-bearing slope to generate a vertically downward component force and a horizontally inward component force, thereby pressing the dovetail block 23 tightly into the dovetail groove 24.

[0027] As a preferred embodiment, in response to the various operational needs at power maintenance sites, the operating head 6 is designed as a replaceable modular component. The operating head 6 is a clamp-type operating head 6, used to perform operations such as gripping foreign objects or wires. The bottom of the operating head 6 is fixedly connected to a universal standard base 22 and a dovetail block 23 by welding. The standard mounting base 21 enables quick interchange of different functional operating heads 6.

[0028] Working principle: When the modular insulated short rod is used for different tasks and the operating head 6 needs to be changed, the operator first rotates the bidirectional lead screw 26 in the reverse direction. The rotation of the bidirectional lead screw 26 drives the two sliders 25 to slide outwards and backwards on the inner wall of the standard mounting base 21. At the same time, the sliding of the two sliders 25 drives the top extrusion block 27 to move outwards synchronously, so that the guide slope on the extrusion block 27 separates from the inner wall of the extrusion groove 28 on the side of the dovetail block 23 of the base 22. The base 22 loses the limiting lock of the two extrusion blocks 27. The operator slides the base 22 at the bottom of the operating head 6, together with the dovetail block 23, along the inner wall of the dovetail groove 24 at the top of the standard mounting base 21 to one side and removes it. Then, the selected new operating head 6 and the bottom... The dovetail block 23 at the bottom of the base 22 is inserted into place along the inner side of the dovetail groove 24. The bidirectional screw 26 is rotated in the forward direction. The bidirectional screw 26 rotates and drives the two sliders 25 to gradually move inward. The two sliders 25 drive the two extrusion blocks 27 to extrude the dovetail block 23 along the inner wall of the corresponding extrusion groove 28. The extrusion force generated by the wedge structure makes the dovetail block 23 and the base 22 firmly locked on the standard mounting base 21. Through the standardized matching design of the standard mounting base 21, the base 22, the dovetail block 23 and the dovetail groove 24, the modular insulating short rod can quickly change the operating head 6 with different functions such as clamp type or fork type according to different operation types, realizing the modular and flexible assembly of the working end of the insulating short rod. When it is necessary to extend or shorten the modular insulating short poles to adapt to different working heights, the splicing mechanism 3 plays a connecting and fixing role. The operator selects an appropriate number of splicing poles 4 according to the height requirements, inserts the positioning pins 37 at the bottom of the splicing poles 4 into the top of the inner wall of the first insulating pole 1 for initial guiding and positioning, so that the fixing rings 31 on the upper and lower poles are close to each other and aligned. Then, the semi-ring sleeve 32 is placed at the interface of the connection between the two poles, and the semi-ring sleeve 33 is rotated to close with the semi-ring sleeve 32 to form a ring connecting sleeve that wraps around the two poles. During the closing process, the annular grooves 34 on the inner walls of the first half-ring sleeve 32 and the second half-ring sleeve 33 accurately engage with the outer wall of the corresponding fixed ring 31. The threaded shaft 35 passes through the second half-ring sleeve 33 and the first half-ring sleeve 32 and the nut 36 is tightened. The threaded fastening force forces the first half-ring sleeve 32 and the second half-ring sleeve 33 to hug the rod body. The mechanical engagement between the annular groove 34 and the fixed ring 31 bears the axial tension. By repeating the above operation, the stable splicing between the first insulating rod 1, the splicing rod 4 and the second insulating rod 5 can be completed, realizing the length adjustment function of the modular insulating short rod.
